Philips Semiconductors
Silicon Diffused Power Transistor
Product specification
BU4508AZ
GENERAL DESCRIPTION
Enhanced performance, new generation, high-voltage, high-speed switching npn transistor in a plastic envelope
intended for use in horizontal deflection circuits of colour television receivers and p.c monitors. Features exceptional
tolerance to base drive and collector current load variations resulting in a very low worst case dissipation.
